Today's topic is all about identifying and eliminating waste, which is one of the key principles of Lean.



▶ Muda

The first type of waste we're going to talk about is Muda.

This refers to any activity that consumes resources without adding value for the customer.

There are two types of Muda: type one, which cannot be eliminated immediately, and type two, which can be eliminated quickly through kaizen.

An example of type one Muda could be an outdated machine that requires frequent repairs and maintenance, but cannot be replaced due to budget constraints.

This is a necessary expense for the time being, but manufacturers can work towards a long-term plan for replacement or upgrade.

On the other hand, an example of type two Muda could be the unnecessary movement of employees and equipment between workstations.

By rearranging the production line or grouping similar tasks together, we can eliminate this waste and streamline the process.



▶ Mura

Moving on, the next type of waste is Mura.

This refers to the unevenness in an operation, which could be caused by an unpredictable demand from customers, resulting in a fluctuation in production levels.

To eliminate this waste, manufacturers can adopt a pull system, where production is based on customer demand instead of a fixed schedule.



▶ Muri

Finally, we have Muri, which refers to overburdening equipment or operators beyond their capacity.

An example could be running a machine for longer hours than recommended or requiring an employee to work in multiple departments simultaneously.

This can lead to poor quality, increased risk of injury, and decreased productivity.

To reduce Muri, manufacturers can invest in training, automation, or hire additional staff.
